TooL-DIn'Eo'r-ING MAcHiNE.

To all whom 'it mag/concern: v Be it known that I,` PATRICK J. OBRIEN, a subject of the King of Great: Britain. residing at Elyria, in the county of Lorain vand State of Ohio, ".lnew and useful Improvements. in'Tool-Directin Machines; and I do hereby declare the'fo lowing to be a full, clear, and eXactvdescription of m invent-ion, suchv as will en- 10 able; others' skil ed the artto which it ap ertains to make and use the same.

Iy` invention relatesto devices for accurately directing tools, such for example as wish to be limited to any particular class of tool. .'Injsoine classes ofwork it is desired to drill holes or vdo other operations'upon work The ordinary machines are not accurate enough to do this work asdesired. V.

My invention aims to produce a' 'device which. provides .an arrangement o apparatus for 'accurately directing the tools-to I. 7 the desired point on the work.

' I' also provide a device which is accurate, which admits of adjustments, which 1s cheaply and easily constructed and which` v maybe handled by people who are vcapable L f of handling such machines as I have described.' i

I also provide means for keeping the adg'justm'ents. proper and for taking.v up wear and change ofV dimensionsdue to atmosf E' pheric conditions.

3 5, My invention and'objects thereof, will be best-understood by reference to the Vdetailed description when taken in connection with vthe drawing. I- have -made these objects though I do not wish it understood that as' Idesire to realize all the ends which my i 'j |means are capable of.

tools directed byfmy--device and which will i is shown at 1. This frame is supported upon legs'Z. Pillars 3 are erected from the frame.

The -machine is placed-upon.' a drill table lin such away that it is supported bythe legsv i .of the machine', which restsjupon :the table.

The bottom of the frame is perforated at 4.-

Upon onel side of the frame I show a pointer .5. A worm Gg'irded upon a worm shaft 7 is i' mounted in'hangers 8, .which vare fastened 70 by screws to thebottom of the frame. "A

support. 10 is mounted in the frame. Aprojection v11 on the bottoni of this support prof jects through the opening 4' 'in the bottoni: of the frame. A Worm gear .12' is :keyed on this projection by a key 13( The lower end of the projection isthreadedand a look nut'- '14 screwed-,thereon to `hold the worm lgear in position., The. Worm gear meshes with` the 'Worm 6. '.A scale 15 is shown upon one edge ofthe support 1() and cooperates with the pointer A5. It will be 'Seen that thesuplport is .rotated in the .frame by `the worm .6,

the amount of rotation being accurately determined from the 'cooperating `scale l-and the lpointer 5. Clamps ljare shown in the frame which lap over the edgefof v,the support assisting to hold the same in position. 'Aturret is shown in the centerlofthis support. This turret is cutaway at'18 land a threaded shaft 19 having each end jourf vnaled inthe edge of-the turretll is' mounted in this opening. A micrometerftlisk 20 is fastened 4upon the' end of theffshaft '19, so .that

the two movetogether. 'Phe'di'sk is" held95 i upon thev shaft by la lock nut 21.. .A pointer 22 mounted` upon the support ooperates' -with the diskto enable the'ope'rato'r to `a'c curately determine-"the distance lthrough whichv the disk is rotated. L Theshaft 19 is' enlarged at-one end,'as shown at. 23.," -Two locknuts 24 are shown upon the enlarged i end of the shaft and normally abut against i the inside ledge of the turret,lholdingythe i shaft accurately inthe proper position.-

These nuts turn with the shaft." lThe turret,

is beveled assliovvn at 25. vA base-member..

26 oppositely beveled at 27 'is mountedupon t-he support. vThe base is adapted to slidev upon the support,-engaging the beveled por-v tions which'act'as guiding ways. At 30 Ig show a key which fitsv between theb eve'ledj'` surfaces o f-th'ese two p ar ts and whichen-ifnfthe base and projects therefrom into the the bridge and' hold it 1n serves as a guiding way for a device. which along the support. T-slots 34 are cut in the 4the stationary jaw. The work or the maables me to adjust the parts so as to take up losses due to general wear, tempera-ture, etc. A lug 31 is mounted upon the bottom ofopening 18 in the support. This lug is pierced and a threaded bushing 32 fastened therein. This bushing is-threaded to engage the threads of the shaft 19.

32 is an adjusting device for taking up the losses or gains due to Wear, 'temperature, etc.

The bottom of the base vis hollowed as shown at 33, to permit the base to slide forward otjer the micrometer'disk 20. Vhen the micrometer disk is rotated, the 'threaded shaft will turn in the lug 31, giving the base a rectilinear motion backward and forward top of the base. Clamps 35 are mounted upon the to-p of the base. Bolts 36 pass throu h the lower limbs 37 of these clamps into te slots in the base, the heads 38 of the bolts fitting in the slots.l The clamps are drawn to the base by nuts 39 on the bolts. It vwill thus be seen that the clamps have a movement along the support in a direction perpendicular to the plane of the paper in Fig. 2. The upright arms 40 of these clamps are pierced and bolts 41 mounted therein. The .heads 42 of these ybolts serve as clamping jaws. The center of the up right limbs is cut away, as shown at 43 and nut 44 threaded on the bolts. mounted in these openings. By turning the nut 44, I realize a finer adjustment of the jaw. 4 2. These jaws coperate with a stationary jaw 45 on the. opposite side of the base. -At 46 I show a facing fastened by a screw 47 to terial upon which work is to be done, which for the 'sake of convenience I here call the work, is clamped between these jaws. It will be readily seen. without describing the o eration that this Work may be rotated a out an axis through the center of the projectionV l1` and 4may be moved rectilinearly in a direction erpendicular to the plane of the paper in 2.

A bridge 50 is hinged, as shown at 51 upon two of the standards 3, As will be readily seen, this bridge can be rotated about a horizontal axis and is lifted up to allow the work to be placed upon the base.

The opposite standards are cut away to allow the bridge to fit closely therein when placed in normal position. Clamps 52 are mounted upon these opposite pillars to-grip l position. Winged nuts 54 are employed to tlghten'the clamps 52. A substantiallyrectangular opening 55 is cut in the central part of the bridge.

Each side 56 of this rectangular openingA will be described hereinafter. Beveled slots 57 are cut in `each 'of the inner edges of the guiding ways. A threaded shaft 58 is journaled in this opening, parallel to the guidinv' ways, each end of the shaft being journa ed at 59 in one of the ends of the bridge. A micrometer disk 60, is mounted upon one end' of this shafty and coperates with a Apointer 61 o n the. bridge. Locknuts 62 hold.

shaft 58 so that the slide is moved along the bridge when the micrometer disk is rotated. The edgesof the slide lap over the top -of the bridge, as shown at 70. Pointers y71 are mounted upon the edge of the slide, the front with a scale 72 upon one l,

one coperating side'of the bridge. A key 74 isemployed between the slide and the bridge to take up adjustments due to wear, temperature, etc.

A vertical hole is lbored at 76 in the slide.

This hole is partly threaded and a threaded In the 78 is bushing 77 screwed into the hole. other part of the hole, a second bushing mounted. The bushin 77 carries a knurled portion' 79. This bus ing 77 is removably fastened in the slide and may b e taken out and other bushings substituted. The bushing 78 serves to accurately aline the removable bushing. The bushing 79 operates to accurately direct the tool. I have shown a bushing for this purpose, because this is the best means for directing a tool which occurs to me.` I intend to employ any device which will serve this purpose and may use thebare opening in the slide withoutdeparting from the spirit of my invention.

90 1s a lock nut for holding theslide and is similar to that shown at 32. A threaded shaft 91 is rigidly mounted upon the slide. A key 92 is mounted in the beveled slot in one of the guiding ways. An arm 93 pro# jects from this key. The key 92 abuts against the slide and moves therewith. Both the slide and the key are tapered to permit the key to glide up on the slide along this tapered portion. Nuts are mounted onnthe threaded shaft on oppositesides of the arm 93. Final adjustments may be given the slide by 'employing this device.
